Alar cartilage

Alar Cartilage

The alar cartilage is a significant component of the anatomy of the nose. It is a flexible structure that provides shape and support to the nostrils, also known as the alae. The alar cartilage is a pair of soft, triangular-shaped tissues located at the tip of the nose.

Structure

The alar cartilage is composed of two separate pieces of cartilage, the lateral and medial crura. The lateral crura extend from the tip of the nose to the outer nostril, while the medial crura connect at the columella, the fleshy external end of the nasal septum.

Function

The primary function of the alar cartilage is to maintain the shape of the nostrils and contribute to the overall form of the nose. It allows for the flexibility and movement of the nostrils, which is essential for breathing and facial expressions.

Clinical Significance

Damage or deformities of the alar cartilage can significantly impact the appearance and function of the nose. Conditions such as rhinoplasty, nasal trauma, and congenital deformities can affect the alar cartilage. Treatment options may include surgical intervention to repair or reshape the cartilage.
